Used as a flame retardant in plastics, rubber, textiles, and coatings due to its ability to release chlorine radicals that inhibit combustion. Commonly added to PVC, adhesives, sealants, and paints to improve fire resistance. Also serves as a plasticizer to enhance flexibility and durability in polymer products. In industrial applications, it functions as a lubricant additive and extreme pressure agent in metalworking fluids. Its low cost and effectiveness make it widely used in cable compounds, flooring materials, and conveyor belts where fire safety is important.
